It finally happened over a year now and my first mistake happened. It was my fault because when you return home it will hover 10 feet it barley hit a tree i think i than landed it and it landed but than took off again on its own flipped over and now need to replace all four props. Question is when you order new ones do you need to order two pairs meaning does it come with 2 props or 4 props and do you need to order two CCW Black ones and two CW white ones or will one "pair" come with two white and black. Thank you again. This was my first mishap since i got it so i consider myself lucky compared to some with just needing new props. I am also in the works of a new short i will post all aerials shot with the Solo
